Floyd Mayweather tells Jimmy Kimmel he'll pay him back if he bets on him and loses

Floyd Mayweather has been known to bet on himself in the boxing ring, and with a record of 49-0, it has paid off for him every single time.

But as safe a bet Mayweather has been in the ring, on Tuesday night while talking to Jimmy Kimmel, Mayweather made it an even safer one, at least for the late night host.

Kimmel revealed that he was considering wagering, saying “I feel like I might bet a lot of money to win a little money on you.”

Mayweather is currently around a -550 favourite in Vegas, meaning bettors would have to bet $US550 to win $US100.

“It’s worth it,” Mayweather was quick to reply. He then went on to assure Kimmel’s bet even further saying, “Whatever you bet, if you don’t win, I’ll give it back to you.”

“Really?!” replied Kimmel, “This is the best deal ever.”

It really would be if Floyd is true to his word. With Mayweather looking to become a career billionaire after collecting his purse for the fight, chances are reimbursing Kimmel whatever he lost wouldn’t dent his net worth that much.

Kimmel then went on to try and get some advice on prop bets for the fight, asking Floyd if he believed he would knock out McGregor, which he refused to answer, or if he believed there was any chance the fight would go the distance, to which Floyd replied, “Absolutely not.” Mayweather was also hesitant to say whether or not Justin Bieber would once again accompany him to the ring.

Chances are Mayweather is playing his cards pretty close to the chest here, but for any die-hard gamblers out there, every scrap of information you can gather is valuable.
